The truck was traveling south at a high rate of speed on Fly Road when Davis lost control, deputies said. The truck left the road, struck a fence and then hit two trees in succession with enough force to rip the engine block from the vehicle, deputies said.

Deputies are continuing their investigation into the crash, Sgt. John D'Eredita said. Part of the investigation will focus on what the two were doing before the crash.

Autopsies are expected to be performed either Sunday or Monday, D'Eredita said.
